MAX38903x Low Noise LDO Linear Regulator

Analog Devices MAX38903x Low Noise LDO Linear Regulator delivers up to 1A of output current with only 7μVRMS of output noise from 10Hz to 100kHz. This regulator maintains ±1% output accuracy over a wide input voltage range, requiring only 100mV input-to-output headroom at full load. The Analog Devices MAX38903x features a programmable soft-start rate, overcurrent protection, overtemperature protection, and output-to-input reverse-current protection. Typical applications include communication circuitry, audio systems, and high-resolution data acquisition systems.
